UNITED STATES PATENT OFFICE SHUTTLE E Carl Aron Anderson, Putnam, Conn.

Application May 16, 1941, Serial No. 393,729

This invention relates to shuttles, and particularly to the type of shuttle adapted for selfthreading automatic looms. I An object of my'invention is to provide a shuttle which will weave from the middle of the shuttle and thus keep the thread away from the box front and prevent the filling from getting caught between the shuttle and the box front when the loom changes bobbins.

Afurther object is to provide a shuttle with a reversible eye adapted to handle thread wound in either direction on the bobbin.

A further object is to provide a shuttle in which the eye is not only reversible but self-threading, and in which the eye may be quickly and simply reversed.

Another object is to provide a shuttle'in which the eye is positioned simply and accessibly.

Other objects will appear from the accompanying drawing, in which- Fig. 1 is a plan view of a shuttle embodying my invention, partly broken away to show the positioning of the thread;

Fig. 2 is a side view of the shuttle, partly broken away to show the positioning of the eye;

Fig. 3 is a detail view of the eye in one position;

Fig. 4 is a detail view of the eye in reverse position.

My improved shuttle has the usual shape and 3 body member 10 with positioning means II for the bobbin l2. Thread I4 is wound around the bobbin l2, passes through the eye !5, over the guide member l6, back through the channel l1,

and out through the slot l8 in the side of the I shuttle. Thread weaving out from the middle of the. shuttle stops the filling from getting caught between the shuttle and the' box front when the loom changes bobbin, and thus eliminates drag-ins. This structure likewise eliminateskinks and gives a more uniform tension.

The'eye I 5 may be made of any suitable sheet ving, such as brass, and consists of a series of convolutions. Commencing at the inner end 20, the metal is formed into a series of convolutions 2| and 22 to form a spiral for the thread. It is then bent upon itself at 23 to form a laterally outwardly extending flange 24, and brought around the outside of the spiral and bent upon itself at 25 to form a laterally outwardly extending flange '26 and a lip 21, which prevents the thread from retreating before the eye is fully threaded. The flange 24 is provided with a per- 3 Claims. (Cl. 139-496) foration or hole 30, and the flange 26 is provided with a similar hole 3|.

The eye is positioned in the shuttle in the groove 39. A member 35 is positioned in the front of the shuttle l0 ahead of the eye, and has an extending arm 36 carrying the pin 31. The member 35 is positioned in the shuttle by means of the screw 38 which extends through the wall of the shuttle. The pin 31 engages the hole 3| when the eye is in position to receive the thread having a counter-clockwise spin, and engages the hole 30 when the eye is in the reverse position to receive thread having a clockwise spin.

When it is desired to change the eye from left to right-hand twist, or vice versa, it is merely necessary to loosen the screw 38, lift the pin 3! out of the hole 30 or 3|, remove the eye, reverse it, replace it, and then tighten the screw 38.

In operation it will be seen that once the thread passes the lip 21, it cannot reverse, but the natural ballooning of the thread will cause it to follow the channel 28 until it has reached the center of the eye.

It will be appreciated that the eye I5 is not limited to my particular type of shuttle, where the thread weaves out of the side of the shuttle, but is equally applicable to shuttles where the thread weaves out from the end, and its reversible nature makes it suitable for use in many combinations.

I claim:

1. In a shuttle, a reversible eye, said eye comprising a piece of sheet material bent upon itself .to form a spiral, opposing flanges at the top thereof, one of said flanges constituting a lip, and reversible fastening elements in each of said flanges.

2. In a shuttle, a reversible eye, said eye comprising a sheet of material bent upon itself to form a spiral, the end ofsaid material being bent to form a spiral, and opposing flanges on the top thereof, one of said flanges constituting a lip;

CARL ARON ANDERSON.
